# Cooling Down with a Fan

Easy
Ever wonder if a fan can really cool you down? Let's find out! In this experiment, we'll compare two pans of warm water. One will be placed in the path of a fan, and the other will be left alone. We'll measure the time it takes for each pan to evaporate and see if the fan makes a difference.

## Hypothesis

The hypothesis is that the pan with the fan blowing on it will evaporate more quickly than the pan without the fan.

## Method & Materials

You will place two pans of warm water 16 inches apart. One will be in the path of a fan, and the other will be left alone. You will measure the time it takes for each pan to evaporate and record the results.
You will need two pans, a fan, a thermometer, and a timer.

## Results

The results showed that the pan with the fan blowing on it evaporated 5.170 times faster than the pan without the fan. This suggests that the fan is able to evaporate the water quicker, replacing the warm moisture with a cooler layer.

## Why do this project?

This science project is interesting because it shows how a fan can be used to cool down the body.

## Also Consider

Experiment variations to consider include using different temperatures of water and different speeds of the fan.
